Clinical Knowledge
A 45‑year‑old patient presented with six months of intermittent, dull abdominal pain localized to the periumbilical region, worsening after meals.
I needed to identify the underlying cause while minimizing invasive testing and ensuring timely diagnosis.
I began with a thorough history focusing on diet, bowel habits, red‑flag symptoms, and medication use, followed by a physical exam. I ordered baseline labs (CBC, CMP, ESR, CRP) and a stool study for occult blood and pathogens. Based on initial findings, I proceeded with an abdominal ultrasound to assess hepatobiliary structures, then a CT abdomen/pelvis with contrast for detailed visualization. When imaging was inconclusive, I referred the patient for an upper endoscopy and colonoscopy to rule out mucosal disease.
The workup revealed mild gallbladder sludge but no obstruction; colonoscopy identified microscopic colitis, which was treated with budesonide, leading to symptom resolution within four weeks.

During my fellowship, several novel biologics and small‑molecule agents for IBD were approved, creating uncertainty about optimal sequencing.
I needed to ensure my patients received the most effective, evidence‑based therapy while balancing safety and cost.
I subscribed to key gastroenterology journals (Gastroenterology, Gut), attended annual ACG and ECCO meetings, and participated in a regional IBD consortium that shares real‑world outcomes. I reviewed latest guideline updates and critically appraised pivotal trials using the GRADE framework. For each patient, I discussed therapeutic options, incorporating disease severity, comorbidities, and insurance coverage, and documented shared decision‑making in the EMR.
By integrating up‑to‑date evidence, I increased the proportion of patients achieving remission from 58% to 73% over 12 months, while reducing steroid dependence by 30%.

Patient Communication
A 60‑year‑old man with non‑alcoholic steatohepatitis was found to have early cirrhosis on imaging and labs.
I needed to convey the seriousness of cirrhosis, discuss lifestyle changes, and outline surveillance without causing undue panic.
I scheduled a private, uninterrupted session, used plain language to explain liver fibrosis, and employed visual aids showing disease progression. I emphasized modifiable risk factors, offered a structured diet and exercise plan, and introduced a surveillance schedule for hepatocellular carcinoma. I invited his spouse to the discussion and provided written resources for reinforcement.
The patient expressed relief at having a clear plan, adhered to lifestyle modifications, and remained compliant with surveillance visits over the next year, with stable liver function tests.

A 28‑year‑old Muslim woman with ulcerative colitis required a low‑residue diet during a flare, but observed Ramadan fasting.
I needed to respect her religious practices while ensuring adequate nutrition and disease control.
I consulted with a dietitian experienced in culturally appropriate meal planning. Together we designed a pre‑dawn (Suhoor) and post‑sunset (Iftar) meal schedule that met caloric needs, incorporated low‑residue foods, and avoided trigger foods. I provided educational handouts in Arabic and scheduled a tele‑visit to monitor symptoms during the fasting period.
The patient successfully completed Ramadan without a flare, reported improved symptom control, and expressed gratitude for the culturally sensitive approach.

Research & Education
During my fellowship, I led a prospective cohort study on the efficacy of fecal microbiota transplantation (FMT) for refractory Clostridioides difficile infection.
My goal was to design the protocol, obtain IRB approval, and generate publishable data that could inform practice guidelines.
I drafted the study protocol, performed power calculations, and coordinated with the microbiology lab for stool processing. I secured IRB approval, recruited 60 patients, and managed data collection using REDCap. I presented interim findings at the ACG conference and co‑authored a manuscript submitted to Clinical Gastroenterology and Hepatology.
The study demonstrated a 90% cure rate with a single FMT, influencing our institution’s standard of care and leading to a new clinical pathway for C. difficile management.

I was assigned to teach a group of 12 third‑year medical students during their gastro rotation.
Create an engaging, evidence‑based session that covered initial assessment, diagnostic workup, and management algorithms for upper and lower GI bleeding.
I organized a 45‑minute interactive workshop using a case‑based approach. I began with a brief didactic overview of hemodynamic assessment, then presented two simulated cases (one upper, one lower bleed). Students worked in small groups to develop differential diagnoses, order appropriate labs/imaging, and outline resuscitation steps. I facilitated discussion, provided real‑world pearls, and concluded with a quick quiz using audience response technology to reinforce key concepts.
Post‑session quiz scores improved from an average of 62% pre‑session to 89% post‑session, and students reported increased confidence in managing GI bleeding on the rotation evaluation survey.

Teamwork & Leadership
A patient with severe acute pancreatitis required input from surgery, interventional radiology, and nutrition services. The surgeon advocated for early operative debridement, while radiology recommended percutaneous drainage, and nutrition emphasized early enteral feeding.
Facilitate consensus to deliver the safest, evidence‑based care plan.
I organized a multidisciplinary huddle, presented the latest evidence from recent RCTs, and encouraged each specialist to voice concerns. I highlighted the patient’s hemodynamic stability and the benefits of a step‑up approach. After discussion, we agreed on percutaneous drainage as the initial step, with close monitoring and a contingency plan for surgery if no improvement. I documented the agreed plan and set daily briefings to reassess.
The patient responded well to drainage, avoided surgery, and was discharged after 14 days with full recovery, reinforcing trust among team members.

As a senior fellow, I noticed that several junior residents struggled with endoscopic polypectomy techniques, leading to longer procedure times.
Implement a mentorship program to enhance skill acquisition and overall endoscopy unit efficiency.
I created a weekly hands‑on workshop where I demonstrated polypectomy steps, followed by supervised practice on simulators. I paired each resident with a faculty mentor for one‑on‑one feedback after real cases. I also introduced a logbook to track competency milestones and provided constructive performance reports quarterly.
Procedure time for polypectomy decreased by 22% over three months, complication rates remained low, and resident confidence scores improved by 30% on the endoscopy skills survey.
